为了有效地检测红外焦平面阵列的盲元，文章提出一种的新的盲元检测算法。该算法利用红外焦平面阵列成像系统在实时成像过程中有效像元和盲元在不同积分时间下响应的差异性，实现盲元的准确检测。实验结果表明：该算法能有效地定位盲元，且不需要黑体辐射源，操作简单，在实际工程中具有较大的应用价值。

In order to effectively detect blind pixel for IRFPA, a new algorithm of blind pixels detection is pres- ented. The algorithm, which makes use of the difference of responsivity between effective pixels and blind pixels on different integration time during IRFPA real-time imaging, can realize the accurate detection of blind pixels. The experimental results show that this algorithm can effectively locate blind pixels without the use of a black body and has the advantages of simple operation with great application value in practical projects.
